I have bought the original and perorin mouths of truth along with this one and for me personally, this one is the best one! I am of average size, but on the thinner side and this tight mouth wraps perfectly around me. Compared to the other ones, the teeth are really soft to the point where you barely feel them, so it's good for longer sessions without it irritating your member. Overall, this is a 10/10 blowjob onahole
My new favorite Mouth of Truth. It's closest competition is the Perorin classic. I haven't tried the other Guchi minis, so I can speak to any differences there. Its interior looks similar to the Perorin Hard type, but is a much gentler experience. If this is due to the material being slightly softer, or there simply being less of it, I do not know. On that note, due to this having less material than the full sized Mouths, I find it easier to maneuver. Good grip and suction. I will be replacing this when it wears out.
